AN12321 NTAG 424 DNA (TagTamper) features and hints - LRP mode Application note
●Introduction
■LRP can be found:
▲About this document
◆This document addresses developers who are developing LRP algorithm for secure messaging on NTAG 424 DNA.
▲LRP facts
◆LRP is a software protocol built on top of well-known cryptographic constructions(AES).
◆LRP is a Pseudo-Random-Function (PRF). A PRF is an efficient, deterministic function that maps an input to an output.
◆LRP operates on an input block size of 16 bytes, the same as for AES. LRP partially re-uses the structure of AES and also calls the AES encryption and decryption functions several times
▲Key benefits of using LRP
◆LRP provides leakage resilience
◆provides fault attack security
◆provides side-channel attack security
◆can be used as a drop-in replacement for AES
